Clear pixel in bitmap texture...

Think scratchcard...
I am trying to clear a pixel (or set of pixels) in a bitmap texture that overlays another bitmap texture when I touch the screen, so that when it is cleared you can see through it to the back bitmap thus revealing prizes.
Sounds easy I first thought, but after using Pixel method it's no good because I am limited by size of the overlay graphic dimensions and also it is too slow on real device I found anyway even with a small overlay that is scaled using pixel lib as per pixelsclown example.
I tried the media library which works but not in the way I want at all.
I thought there was a Texture:setPixel(value) or Texture:setPixel(alpha) but it seems not as far as I can tell?
Stumped :P
